Hygrade CPA370 Carburetor Choke Pull-Off

Carburetor Choke Pull-Off for Rochester Carburetors

The Hygrade CPA370 carburetor choke pull-off is a valve-style replacement for Rochester carburetor applications across a wide range of Chevrolet, GMC, and Dodge trucks and vans. It helps restore proper choke operation on carbureted engines when cold-start performance, idle quality, or choke release timing becomes inconsistent.

• Carburetor choke pull-off valve for Rochester carburetor systems
• Fits select Chevrolet, GMC, and Dodge applications from 1981-1989
• Direct replacement for many alternate and cross-reference part numbers
• Supports proper choke opening after startup on M4ME, M4MC, E4ME, and related Rochester carburetors
• Hygrade aftermarket coverage backed by a manufacturer serving the automotive aftermarket since 1919

Detailed Product Overview

Hygrade CPA370 is built for carburetion service where the choke pull-off valve must respond correctly during cold starts and warm-up. This part is listed for numerous Rochester carburetor-equipped Chevrolet C10, GMC Jimmy, and Dodge D250 applications, along with many other truck and van platforms. If your vehicle shows hard starting, rich running after startup, or a choke plate that stays closed too long, this replacement valve addresses the choke pull-off function directly.

This part cross-references Standard Ignition CP446 for the same application.

What It Helps Correct

• Hard cold starts caused by improper choke release
• Rough or overly rich idle after startup
• Choke plate staying closed longer than specified
• Stumbling or loading up during warm-up
• Driveability issues tied to worn Rochester choke pull-off components
